Sorc build: Tazer

[WarBlade]

Actually the plan is fine. My melee Sorceress uses your suggested tactic to great effect with even stronger support from Mana Steal items. With a Prayer merc on the side and some Life Steal in the mix she can basically do the Werewolf thing of tanking by leeching back faster than getting hurt unlike the more traditional melee Sorceress tactic of relying on heavily Defence to protect.

Additionally Warmth can assist in support of ES too, albeit to more of a backup or in-between-fight degree.
